Description
The AT1781 is an FPGA Configuration EEPROM that provides a cost-effective memory solution for Field Programmable Gate Arrays. It features a simple serial-access procedure to configure one or multiple smaller FPGAs. The AT1781 has enough memory to configure one or multiple smaller FPGAs and uses a simple interface to SRAM FPGAs, requiring only one user I/O pin. Additionally, the AT1781 is compatible with various FPGAs, including AT6000 FPGAs, ATT3000 FPGA, EPF8000 FPGAs, ORCA FPGAs, XC2000, XC3000, XC4000, XC5000 FPGAs, and MPA1000. This electronic component has a programmable reset polarity, is available in 3.3V ± 10% LV version, and can be programmed through the industry-standard programmers.
